Scan Tool Data Definitions

This parameter displays On when the transfer case shift control module commands the 2WD high indicator light On. The scan tool displays On or Off.

This parameter displays On when the transfer case shift control module commands the 4WD high indicator light On. The scan tool displays On or Off.

This parameter displays On when the transfer case shift control module commands the 4WD low indicator light On. The scan tool displays On or Off.

This parameter displays Not Active, and Active.

This parameter displays Not Initialized, Passed, Failed, or in Progress when the key off initialization sequence has occurred.

This parameter displays On when the transfer case shift control module commands the auto 4WD indicator light On. The scan tool displays On or Off.

This parameter displays the voltage measured by the transfer case shift control module at the transfer case shift control module battery feed. The scan tool displays a range of 0-25.5 volts.

This parameter displays not learned, initial learn, and normal learn.

This parameter displays the amount of clutch activation shown in percentage.

This parameter displays the voltage input to the front axle actuator from 0 - 25 volts.

This parameter displays either disengaged or engaged, engaged when the system is in Auto 4WD, 4WD, or 4WD Low modes, and disengaged when the mode is in neutral, or 2WD mode.

This parameter displays either locked or unlocked depending on the feedback from the front axle actuator switch, which will be battery voltage when the vehicle is in a 4WD or Auto 4WD mode.

This parameter displays the direction the incremental sensor is moving as clockwise or counter clockwise.

This parameter displays the pulse width modulated voltage signal being supplied to the incremental sensor via the transfer case control module.

This parameter displays the position of the incremental sensor in degrees.

This parameter displays the position of the incremental sensor in incremental sensor return voltage.

This parameter displays the transfer case shift control switch return voltage from 0-7.5 volts.

This parameter displays the transfer case shift control switch mode currently selected by the driver.

This parameter displays the voltage being supplied to the transfer case shift control switch by the transfer case control module from 0-7.5 volts.

This parameter displays the voltage being supplied to the transfer case motor brake via the transfer case control module from 0 to battery voltage.

This parameter displays On when the transfer case shift control module commands the neutral indicator light On. The scan tool displays On or Off.

This parameter displays the position of the rotational position sensor in degrees.

This parameter displays the position of the rotational position sensor by displaying the rotational position sensor return voltage as read by the transfer case control module.

This parameter displays the status of the run/crank signal to the transfer case control module as active or inactive.

This parameter displays the status of the transfer case lock as engaged or disengaged, the lock will be engaged in auto 4WD, 4WD, or 4WD low and disengaged in 2WD and neutral.

This parameter displays the current draw in amperage that the motor is currently drawing from the transfer case control module.

This parameter displays the current mode the transfer case is in as indicated by the transfer case control module.

This parameter displays the transmission fluid temperature in degrees Celsius.

This parameter displays the current gear the transmission is in.

This parameter displays vehicle speed in kilometers per hour.

This parameter displays the numbers or characters assigned to the current version of software used in the transfer case shift control module. The scan tool displays an alphanumeric value.

This parameter displays the total slippage of both the front and rear propshafts. The scan tool displays a range of 0-8,192 RPM.
